Family PETRICOLIDAE. 
358. Petricola lapicida, Chemnitz, 40,a, X/X. II, VIII, XV. 
Family PSAMMOBIIDAE. 
359. Psammobia rugulosa, Adams and Reeve, 37,X. X. 
360. Psammobia pulcherrima, Deshayes, 37, X, 39,a. X. 
The Maldive specimen is considerably larger than the type described by Deshayes, being 
31 millim. long, and 16 broad. It is whitish with several irregular somewhat broken purple red 
rays which are also visible upon the inner surface of the valves. The scales upon the posterior 
costae become obsolete as the shell increases. 
361. Asaphis deflorata, Linn. (Capsa dejflorata, Reeve, 37,X). IX. 
Family ROCELLARIIDAE. 
362. Rocellaria gigantea, Deshayes (Gastrochaena gigantea, Sowerby, 190,a, XX). IX. 
363. Rocellaria mytiloides, Lamarck (Gastrochaena mytiloides, Sowerby, 37,XX). XII. 
Family MESODESMATIDAE. 
364. Paphia trigona, Deshayes (MJesodesma trigona, Reeve, 37, VIII). IX. 
365. Paphia glabrata, Gmelin (Mesodesma glabrata, Reeve, 37, VIII). IX. 
Family LUCINIDAE. 
366. Lucina (Codakia) divergens, Philippi, 33,}. (Lucina fibula, Reeve, 37, VI). IX. 
367. Lucina (Codakia) punctata, Linn. 37, 7. IX. 
368. Lucina (Divaricella) dalliana, Vanatta var. 42. IX. 
Three valves from the Maldives are a trifle more globose than 8. African specimens, the 
divaricating lines are rather less numerous, and the smooth band, where they meet, is not quite 
so evident. In typical and especially in young examples the posterior straight dorsal margin forms 
a rounded angle where it meets the posterior curved outline. This angle is less apparent in the 
Hulule specimens. 
The very fine crenulation within the margin of the valves is similar in both forms. 
This species has been erroneously quoted by Mr Sowerby as JL. quadrisuleata, d’Orbigny, 
(Marine Shells S. Africa, Appendix, p. 26). Of this I speak with certainty as the shells so-named 
by him are now in the British Museum. 
369. Cryptodon globosus, Forskal (Lucina globosa, Pfeiffer, 32). IX. 
Family TELLINIDAE. 
370. Tellina elegans, Gray, 40,0, XVJ/. IX. 
371. Tellina crucigera, Lamarck, var. wmoena, Deshayes, 37, XVZ/. IX.
